Beta Company is taking pre-orders for a C-MAG for the 9mm Glock. This huge magazine weights two pounds (unloaded) and holds 100 rounds of 9mm Luger/Parabellum. It is shipped with a magazine loader, a pouch and tubes of graphite. At $390 (for the clear plastic back model) it is not cheap, but then neither is dumping 100 rounds of ammo. The magazine ships in 12 – 16 weeks.
If you already own a 9mm C-Mag for another gun, FirePower Solutions have developed a range of magazine adapters that allow the 100 round 9mm Beta C-MAG to work with the Glock 17, 18 and 19 and unlike the Glock C-MAG, is available now.
It is sad that magazine technology has come so far in the past few decades, but magazine loading technology has not caught up. This magazine is crying out for a robotic magazine loader
